Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, and particularly relates to an automatic calibration device for pump liquid of a cooking machine. Background Art

[0002] In the prior art, most automatic cooking machines use peristaltic pumps and pipeline systems to achieve the addition of seasonings, that is, during the cooking process, according to the preset dish program, various seasonings such as brine, monosodium glutamate water, light soy sauce, edible oil, soy sauce, and thickening juice are accurately added in sequence. However, due to the characteristics of the peristaltic pump, it often shows varying degrees of attenuation after long-term use, which will obviously lead to deviations in the amount of seasoning added. The deviation in the amount of seasoning added will ultimately result in the taste of the dish not meeting the expected requirements. Taking the addition of brine as an example, if too much brine is added, the dish will taste too salty; on the contrary, if not enough brine is added, the dish will taste too light. The same situation applies to other seasonings.

[0003] Currently, in order to solve the above problems, the peristaltic pump needs to be manually calibrated every day. That is, before the automatic cooking machine starts cooking officially, the staff needs to manually weigh the weights of various seasonings sprayed by the cooking machine and compare them with the expected values. For example, the operator first issues an instruction to the cooking robot to control the peristaltic pump (seasoning pump) to spray 10 g of brine, and then manually uses an electronic scale to measure the actual weight of the sprayed brine. If the actual measurement result is consistent with 10 g, it indicates that the corresponding peristaltic pump is operating normally; if there is a difference, the staff needs to manually adjust the parameter value of the corresponding peristaltic pump to ensure the accuracy of the peristaltic pump for transporting liquid materials. Since there are many types of seasonings, and each seasoning may have multiple weight gears that need to be calibrated, the operation of the entire calibration process is relatively cumbersome and time-consuming. It is statistically shown that it takes at least 30 - 40 minutes to calibrate one machine manually. It can be seen that the manual calibration method not only increases the work burden of the staff but also affects the customer satisfaction with the automatic cooking machine products. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above deficiencies of the prior art and provide an automatic calibration device for pump liquid of a cooking machine, which can be used to improve the calibration efficiency of the seasoning pump of the cooking machine and reduce the work burden of the staff.

[0005] The technical solution of the utility model is: an automatic calibration device for the liquid pumping of a cooking machine, including a material box and a bracket; the material box is located above the bracket; the material box is used for loading the seasonings sprayed from the cooking machine; the bracket includes an upper part and a lower part, the upper part of the bracket includes a first box body, and a weighing mechanism is arranged in the first box body. The weighing mechanism is used to weigh the weight of the material box, and the weighing mechanism is connected to the calibration main board through a cable. The weighing mechanism feeds back the weight information of the material box to the calibration main board; the lower part of the bracket includes a second box body, and the calibration main board is installed inside the second box body. The calibration main board is connected to the control main board of the cooking machine by a communication line; wing plates are arranged on both sides of the second box body, and the two wing plates are used to lap on the edge of the cooking pot of the cooking machine so that the whole calibration device is fixed on the cooking pot.

[0006] Further, the calibration device in this application further includes a filter screen, and the filter screen is located at the opening above the material box and is used for filtering and preventing the sprayed seasonings from splashing out of the material box.

[0007] Further, the material box is a container with a wider upper part and a narrower lower part. For example: the seasoning box can be trapezoidal or frustum-shaped.

[0008] Further, the shape and size of the first box body are adapted to the material box, so that the material box can be stably fixed above the first box body.

[0009] Further, a calibration program is installed on the calibration main board. The calibration program is used to realize the information transmission between the weighing mechanism and the control main board of the cooking machine. The calibration program is used to make the control main board of the cooking machine issue an instruction to control the seasoning pump to transport seasonings of a specific weight, and then judge the accuracy of the weight transported by the seasoning pump according to the measurement result of the weighing mechanism.

[0010] Further, the calibration program is also used to adjust the parameters of the seasoning pump. Specifically, according to the difference between the measurement result of the weighing mechanism and the predetermined weight of the seasoning pump transportation, the parameters of the corresponding seasoning pump are automatically modified. For example: the issued command is to transport 10g of materials. According to the initial parameters, the rotor of the seasoning pump should rotate 100 circles. However, through the measurement of the weighing mechanism, there are actually only 5g of materials, indicating that the current transportation capacity of the seasoning pump is only half of the original. The rotation parameter (number of circles) corresponding to the seasoning pump transporting 10g of materials should be set to 200 circles, and so on.

[0011] Further, the calibration program is called through the terminal APP or the control panel of the cooking machine.

[0012] Further, the weighing mechanism uses an electronic scale.

[0013] Further, the calibration program is also provided with a voice prompt function. During the calibration process, the calibration progress and results are announced through voice.

[0014] Furthermore, the wing plate is a telescopic plate and can be used to adapt to woks of different sizes.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the liquid pumping automatic calibration device of the cooking machine of the present utility model, only need to connect the communication line of this device with the automatic cooking robot, and select to execute the calibration command through the interface of the relevant APP, then the automatic calibration of the seasoning pump can be carried out throughout the process. At the same time, there is a voice prompt for the calibration progress and result during the calibration process; the time required to calibrate all kinds of seasonings can be shortened to a few minutes, which greatly improves the calibration efficiency, enhances the customer satisfaction, and also saves the time cost.

[0020] The following will further elaborate on the present utility model in detail with reference to specific embodiments. The methods or functional components not specifically described in the embodiments are all prior arts; unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0021] Embodiment 1

[0022] As Figure 1-2 shown, this embodiment is a liquid pumping automatic calibration device for a cooking machine, including a seasoning box 1 and a bracket; the seasoning box 1 is located above the bracket; the seasoning box 1 is used to load the seasonings sprayed from the cooking machine; the bracket includes an upper part and a lower part. The upper part of the bracket includes a first box body 2, and a weighing mechanism 5 is arranged inside the first box body 2. The weighing mechanism 5 is used to weigh the weight of the seasoning box 1, and the weighing mechanism 5 is connected to the calibration main board 6 through a cable. The weighing mechanism 5 feeds back the weight information of the seasoning box 1 to the calibration main board 6; the lower part of the bracket includes a second box body 3, and the calibration main board 6 is installed inside the second box body 3. The calibration main board 6 is connected to the control main board of the cooking machine by using a communication line 8; wing plates 4 are arranged on both sides of the second box body 3, and the two wing plates 4 are used to overlap on the edge of the wok 7 of the cooking machine so as to fix the whole calibration device on the wok 7.

[0023] In this embodiment, the calibration device further includes a filter screen (not shown in the figure). The filter screen is 200 mm long, 188 mm wide, has a pore size of 500 mesh, is made of stainless steel, and the fixed frame of the filter screen has a thickness of 2 mm, also made of stainless steel. The filter screen not only filters impurities but also prevents liquid from splashing out of the material box 1, resulting in inaccurate weighing.

[0024] In this embodiment, the material box 1 is a trapezoidal container with a wider top and a narrower bottom, made of PP (plastic), and its surface is treated with a bright finish. The upper plane of the material box 1 is a rectangular opening with a length of 200 mm and a width of 188 mm, which is adapted to the size of the filter screen for convenient placement of the filter screen. The lower plane of the material box 1 is a rectangular bottom with a length of 124 mm and a width of 108 mm.

[0025] In this embodiment, the shape and size of the first box body 2 in the bracket are both adapted to the material box 1, so that the material box 1 can be stably fixed above the first box body 2. The first box body 2 consists of a cuboid bottom and a trapezoidal top cover with a wider top and a narrower bottom. The cuboid bottom has a length of 101 mm, a width of 60 mm, and a height of 28 mm, and the trapezoidal top cover is consistent with the size of the lower plane of the material box 1, enabling the material box 1 to be placed stably on the first box body 2. The second box body 3 has a length of 135 mm, a width of 106 mm, and a height of 45 mm. The wing plates 4 on both sides of the second box body 3 are symmetrically arranged. The wing plates 4 extend obliquely upward from a side edge of the second box body 3, and there is a bend in the middle of the wing plates 4, so that a part of the plane of the wing plates 4 away from the second box body 3 remains horizontal. The wing plates 4 and the second box body 3 are integrally injection-molded. The upper and lower parts of the bracket are connected by a buckle and a screw method.

[0026] In this embodiment, a calibration program is installed on the calibration main board 6. The calibration program is used to realize the information transmission between the weighing mechanism 5 and the control main board of the cooking machine. The calibration program is used to make the control main board of the cooking machine issue an instruction to control the dosing pump to deliver a specific weight of seasoning, and then judge the accuracy of the weight delivered by the dosing pump according to the measurement result of the weighing mechanism 5. The calibration program is also used to adjust the parameters of the dosing pump. Specifically: according to the difference between the measurement result of the weighing mechanism 5 and the predetermined weight of the seasoning delivered by the dosing pump, automatically modify the corresponding parameters of the dosing pump. For example: the command issued by the control main board of the cooking machine is to deliver 10 g of material. According to the initial parameters, the dosing pump should rotate 100 circles. However, after measurement by the weighing mechanism 5, the actual material is only 5 g, indicating that the delivery capacity of this dosing pump is only half of the original. The rotation parameter (number of circles) corresponding to the dosing pump delivering 10 g of material should be set to 200 circles. And so on.

[0027] In this embodiment, the calibration program can be called through the terminal APP or the control panel of the cooking machine. The weighing mechanism 5 uses an electronic scale. The calibration program is also provided with a voice prompt function. During the calibration process, the calibration progress and results are announced through voice.

[0028] In some other embodiments, the wing plate 4 can be arranged as a telescopic plate structure, and the extension length of the wing plate 4 can be adjusted by telescoping, so that the entire calibration device can be adapted to be installed on cooking machines with various different diameters of the cooking pans 7. A plurality of reinforcing ribs can be arranged on the lower surface of the wing plate 4.

[0029] When the automatic calibration device for the liquid pumping of the cooking machine in this embodiment is in use, the two wing plates 4 can be directly placed above the cooking pan 7 of the cooking machine, so that the seasoning sprayed from the liquid outlet of the seasoning pump of the cooking machine just falls into the material box 1. Then, the calibration main board 6 is connected to the control main board of the cooking machine through the communication line 8. At this time, the calibration program can be called through the APP or the control panel of the cooking machine to perform the calibration operation. The APP and the calibration program can be pre-coded, and the specific coding process adopts the existing technology and will not be elaborated here.

[0030] The above are only some embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have combinations and variations of the foregoing various technical features. Without departing from the spirit and scope of the present invention, improvements, variations, equivalent replacements of the present invention, or the use of the structure or method of the present invention in other fields to achieve the same effect all fall within the protection scope of the present invention.
